Question

in what time will rupees 8500 amount to 15767.50 at the interest rate of 9% per annum​

Answer 1

Answer:

Given principal = ₹ 2750

rate = 10%

Find the simple interest :

-------------------------------

S.I = ( p × r × t ) /100

S.I =( 2750 × 10 × t ) / 100

S.I = ₹ 275 t

since , we know that

amount = principal + S.I

solve for 't' :

-----------------

3575 = 2750 + 275t

275t = 3575 - 2750

275t = 825 => t = 825 ÷ 275

t = 3 yrs

therefore, the required time = 3 yrs

Answer :time = 3 yrs
